LOCOMOTIVE-BOILER.

Specification of Letters Patent.

Patented April '7, 1908.

Application filed'October 29, 1906, Serial No. 341,051. Renewed January 28, 1908. Serial No. 412,992.

To all whom it may concern:

Be it known that I, JosnPn J. GAGE, a citizen of the United States of America, residing at Mansfield, in the county of Rich land and State of Ohio, have invented certain new and useful Improvements in Locomotive-Boilers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has relation to certain new and useful improvements in locomotive first, to provide means to lengthen the life and durability of boiler flues in locomotives; second, to prevent a certain amount of vibration being imparted to the flues when the engine is in motion, and thereby obviating to a reat extent the loosening of the flues 1n the ue-sheet next to the fire box, and preventing leakage.

The construction by which I carry into effect the aims and objects of my invention will be heriflnafter fully described and then specifically claimed, and in describing the invention in detail, reference will be had to the accompanying drawings forming a part of this application, and wherein like numerals of reference will be used to indicate like parts throughout the several views in which:

Figure 1 is a longitudinal sectional view of a locomotive boiler embodying my invention. Fig. 2 is a detached view showing in plan, the plates formin the auxiliary or supplemental support for t e boiler flues. Fig. 3 1s a transverse vertical sectional view thereof, and Fig. 4 is a longitudinal sectional View of a part of one of the flues, showing in vertical section a part of the front fluesheet, and a part of the plates constituting the auxiliary or supplemental support for the boiler flues.

The construction which forms the subjectmatter of the present application is an improvement upon that shown in my prior patent 706,490.

In my present invention I employ an additional intermediate flue-sheet to that shown in my rior patent noted above, which is adjusta le vertically whereby to hold the flues secure, and thereby dispensing with the sleeves shown and described in my former patent, the adjustability of said additional ue-sheet permitting the ready, removalvand replacing of the flues when desired.

The present invention also relates to an improvement in the manner of fastening the ends of the flues in the flue sheets, the present construction embodying a copper ring over the ends of the flues next to the fire box, the beads of the flues being drawn over these copper rings, thereby eliminating possibility of the flues leaking, long life to the beads.

In the practice of my invention as involved in the present application, I provide an auxiliary or supplemental flue support which, in practice, is located usually approximately one-fourth the distance between the two end flue-sheets 1 and 2, as illustrated in Fig. 1 of the drawings. The object of this auxiliary supplemental flue-sheet is to shorten the length of the bearings, by forming a support for the flues 3 between the two end flue sheets 1 and 2. This auxiliary or supplemental flue-sheet comprises two plates 4 and 5. These plates are placed one against the other, in a vertical position within the boiler. The plate 4 is stationary, and may be held so, in any desirable manner, a preferable method bein to provide this plate 4 with apertured flanges 6 to be riveted or otherwise secured to the boiler. At its upper end the plate 4, is provided with a flan e'7, which extends at right angles to theead of the plate. The said plate 4 is provided with openings 8 to receive the flues 3, which openings, as best seen by reference to Fig. 4, are

of such shape as to allow for slight adjustment of the flues 3 therein. Placed against the one face of the late 4 is an additional flue-plate 5, which, ike the plate 4, is provided with flue openings designated 10, and registering with the flue openings 8 in the plate 4. The said flue openings 10, are shaped similarly to the flue openings 8. The plate 5 carries a flange 11, which, like the flange 7 on the plate 4, extends at ri ht angles to the bead of theplate, and ies underneath the flange 7. Bolts 12, are passed through these flanges, and the plate 5 is adjusted up or down by tightening or loosenin nuts 14, on said bolts 12. The plate 5 is he d against the plate 4, and is guided during its vertical movement by bolts or studs 15, carried by the plate 4, and extending through slots 16 in the plate 5.

In Fig. 4 of the drawings, I show an imroved manner of securing the ends of the flues 3 in the end flue-sheet 1, embodying a copper ring 17, which the bead of the flues is swaged over, thus preventing the flues from becoming loose and leaking which is of and giving common occurrence in all locomotive boilers. By the employment of the auxiliary or en plemental support for the fiues 3, It will e observed that the fiues will be to a great extent prevented from vibrating and springing from their normal line when the locomotive is in motion. The openin s 8 and 10, are sufficiently large to permit t e admission and removal of the flues 3 easily, and when the lines are in position they are securely held by tightening nuts 14, so as to draw plate 5 upwardly and bring the lower wall of the openings 10, into contact or engage ment with the fines, at which time the upper wall of the openings 8 in plate 4 also engage the fines 3, as clearly seen in Fig. 4 of the drawings, whereby the flues are securely held.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a device of the type set forth, the combination with a boiler having front and rear heads or flue-sheets, of an intermediate vertical head or flue-sheet secured in front of the rear head or flue-sheet, with a series of horizontal ,fiues passing through all of said heads or flue-sheets, the intermediate head or fine sheet supporting the weight of the lines between the front and rear heads or fiuesheets, and the' said intermediate Head or flue-sheet being a double plate which allows one of the plates to be drawn up or down and which securely fastens the fiues in said inter mediate head or flue-sheet.

2. In a device of the type set forth, the combination with a boiler, having front and rear flue-sheets, and horizontal fines supported in said sheets, of an intermediate supplemental flue-sheet comprisin two plates one of which is stationary within the boiler, and the other of which is movable vertically, the said plates being provided with openings to receive said fines, and means for securing the movable plate in fixed position with relation to the stationary plate.

3. In a device of the t e set forth, the combination with a boiler aving front and rear flue-sheets, and fines supported in said sheets, of an intermediate supplemental flue-sheet comprisin a stationary member, and a movable mem er both provided with openings to receive said fiues, the openings in one member being so disposed with relation to the o enings in the other member that Epposite wa ls of said openings engage the nos.

4. In a device of the ty e described, the combination with a boiler aving front and rear flue-sheets, and fines supported in said flue-sheets, of an intermediate supplemental flue support comprising a stationary plate secured in the boiler, and a vertically movable plate engaging the face of said stationary plate, both of said plates having fiueopenings, means for securing the movable plate to the stationary plate, and means for securing the movable plate in adjusted position with relation to the stationary plate.

In testimony whereof I affix my signature in the presence of two witnesses.
